Simply put, woven polypropylene is
the best material for making bags, especially bags which will contain
large quantities of granular or small-sized products such as pet food,
rice, seeds, charcoal, kitty litter, grain, cement, fertilizer, dry
chemicals, powdered minerals such as gypsum, potatoes, and other similar
products.

Woven polypropylene bags offer many advantages over paper and jute.:

Lighter weight

Much greater bursting strength

Better pest resistance

Resistance to tearing

Reusable

Can be air permeable and moisture, pollutants, bacteria, mildew, and oil resistant

Properties do not degrade if wet

Less expensive

For these reasons, more and more companies are packing their products in
polypropylene bag. This has been especially true in the B2B arena where
appearances are not as important as cost and performance.

Companies
who market to the consumer have not been as quick to make the switch
because paper bag has, up-to-now, been a far better medium for bright
and crisp graphics. However, with our new process of three-layer
bag-making, our graphics are the same as for paper bag. So now companies
can enjoy the benefits of woven polypropylene bag while giving the
customer hard-hitting and beautiful graphics--and all at a lower cost.

Woven propylene (PP) bags

Woven propylene has the strength
necessary for packaging heavy amounts of product. Whereas paper or
Polyethylene (PE) bags often break when loaded with 30 pounds or more of
product, woven polypropylene (PP) can easily handle over 100 pounds.
And now, with the technology available to Lucky Star, woven
polypropylene (PP) bags can look just as good as bags made from other
materials. Strength, durability, and appearance, all in one package.

Some
of the most common uses for woven polypropylene bags include pet food,
rice, fertilizer, animal feed, grains, seed, cement, wood chips,
charcoal, chemicals, and sand. Basically, any product which is packaged
in paper, jute, cotton, or plastic bags can be switched over to woven
polypropylene (PP). The below table gives some typical bag sizes and
capacities.
